Throughout the Various views of the drawings, like reference characters designate like or similar parts.

In reducing the invention to practice, a

suitable casing or'enclosing structure is procasing, a securing latchinthe form of a; lever is pivotedat'ti to a bracket 7 extending'from the base and is engageable with the lug 8 within the casing and adapted to be urged against said lug through the adjustment of a set screw 9 passing through a suitable opening in whichit is threaded to said base 1. It will be realized that normally the screw 9 is retracted tooccupy the dotted line position shown in Figure 3 so that the casing 2'may' be readily attached or detached. VV'hen attached, thel'ug 3 is placed in engagement with theflhook4' and thereafter screw 9 is moved inwardlyto the full line position of Figure 3, thus tightening the latch lever 5 against the lug 8 and mounting-the cover 2 rigidly on the base. 7 j I.

The front of the casing is preferably closed by a glass panel 2 and with the "exception of transparent portions 10,1-2an'd 13 is rendered opaque 'by' the ap'plication-of' a coaching of black paint to the inner surface thereof or in any other suitable manner. The transparent portion 10 has the words T imelfirnd Re cording delineated thereon, between whic'ha sign ll is movable and wh1ch,-1nay contain the word Not to ind cate when the device 15,

and whenit is not -'record-ing. Operating in the rear of the portions 12 and 13 are 're'gis' tering or fare drums 14 and 15,"re'sp'ec'tively.

1 The drums l i' form a register to indicate fare which the passenger normally must pay {and drums 15forin 'a register for extra or fare v tobe added'to that of drums 14 and to be paid; by the same passenger. A plate l'fi'a'lso opero ates in rear of the portion 12 liaving a Zero mark to coact 'with drums 14 always forming the right hand figure as charges always end withfzero; The panels' 2f may rest against lugs a and be'overlapped bya flange 2 and J a elt orother waterproof filler'2? may be i-nterposedbetween the panel 2 andthe' flange 2, as clearlyshown'inFigure 3 of tliedraw g v V p Also visible from the front "of the device is afl'ag'or plate 17 having a stem 18' mounted on a stub shaft 19 ournaled in the base 1.

This flag is in raised position when the ap-' paratusisiiot in service and it is in lowered V position'whent he apparatus is in service.

A switch arm 20 is also visible from the front of the apparatus and is mounted on a stub shaft 21 journaled in said base 1 (see Figures 4 and 9).

a In the base 1 adjacent the lower end thereof isan elongated opening 22 preferably covered by transparent material. Behind the opening 22 and visible from the rear of the apparatus, are groups of recording drums forming a conventional registering mechanism 24.

.Within the casing a disk 28 (Figures 9 and 10) is keyed or otherwise fixed on the stud shaft 19. This disk may slide a limited extent on the key and stub shaft 19 and is normally urged into frictional contact with "the base'1 by means of anexpansive spring 30 interposed between the disk 28 and a flange or head 31 on the stub shaft 19 (Fig- .ure 8) so that it maybe friotionally held or automatically remain in its different posi-,

tions through actuation of shaft 19.

Secured against the base 1 is ablo'ck of insulation 32 (see Figure 9) in which stub shaft 21 is journaled and across which a blade 22 rigid with swi-toh'ar'm 20 is operable. On block 32 a contact 33 is secured while a resilient contact 34 normally disengaged from-contact 33 is disposed over it and relatively close thereto; On the disk 28, an arm 35 is provided. In the pathof movement of said arm 35 contact 34 is disposed so that it will be engaged by said arm 35 in order to move it'irito contact with the element 33. Also mounted on the base' or block 32 are contacts 36, 37 and 38. It will be notedthat when the flag-is rais'ed,'the *arm 35 di'se'ngages contact '34.

and spacedforwardly therefromis a 'sup-' porting plate 39 (Figures 8 and 17-), 'mount- :ed as by means of studs '40 extending from I base 1 and screws 41 extending through Adjacent to the upper end of the base the'supportingi plate 39 and into the studs 3 A suitable electric motor 42 (Figures 5130 8) is mounted in any-approved way from. this plate 39. This motor con'trols'a make and break device for fare registering mechanism when the vehicle equipped with it is not running so as to provide-a charge'for waiting time, and hence switch 20 ,"(Figure is thrown to the right for operation of the registering mechanism when the ve'h icle is running and is thrown to the left when the vehicle is idle as will later become more apparent. The main shaft of motor 42 is from'th'e plate 39. On the shaft 43,1 0 911:

ventional governor mechanism has been illustrated at 45. Journaled in supporting plate 39is a shaft 46, which isalso journa'led in a bracket 47 fastened at 48' to the plate 39. On shaft 46, a gear wheel"49is keyed or fixed which is in the nature 'Of'fi. worm wheel which meshes with aworm 50 keyed shown at 43','as'in Figure 7, having one end ournaled in a bracket 4'4 suitably supported or fixed on the shaft 43. A spurgear wheel or pinion 51 (Figure 10) is keyed or fixed on shaft 46 and meshes with a gear wheel 52 journaled on ashaft 53 extending from plate 39. Extending from gear wheel 52 is a cam stud 54 engageable with a contact 55 of an electric switch completed by a contact 56 (Figures 4 and which is secured to a block of insulation 57 supported on plate 39 as by means of binding screws 58.

v A vertical shaft to operate the registering mechanism as will be hereinafter specifically described, is illustrated at 59. and journaled in brackets or plates 60 and 61 extending outwardly from the base 1. Rigid with shaft v59 is a relatively large ratchet wheel 62 (see Figure 14) which is adapted to be rotated by a step-by-step movement of an armature 63 associated with a double electro-magnet at 64 suitably secured to the base 1. Said magnet 6'4 is controlled selectively by two make and break circuits, one

operated by the motor 42 and the other by the wheels of a taxicab as will later appear so that waiting time as well as running time may be charged. The armature 63 has a mounting arm 65 journaled onthe shaft 59. A preferably. resilient pawl or arm 66 extends from armature 63 and is in normal contacting relation with the teeth of the ratchet wheel 62 so as to turn said ratchet Wheel through movement of the armature 63 caused by the electro-magnet 64. An arm 67 projects forwardly from the base 1 and a contractile spring 68 is secured thereto and to arm 65 to normally maintain the armature 63 away from the magnet 64 and against a stop which limits its'movement and which may be a set screw 69 operatively mounted in an arm 70 of a bracket 71. In

order to prevent retrograde movement of the shaft 59 as the armature 63'is returned to rigid thereon carrying a'pawl 76 to coact with a stud or projection 77 (Figure 7) on shaft 59 so that rotation of the wheel 7 4or plate will turn the shaft 59 in one direction. To turn gear wheel 74 in order to set up a minimum fare, a segmental rack gear 78 is provided and extends rigidly from the anism. These parts are operated only when the cab is idle. L

Said vertical shaft 59' is designed to operate any preferred type of registering mechanism. The actuation of shaft 59 is effected as follows. The flag 17 is thrown to the right in Figures 1 and 7 to occupy a concealed or dotted line position when the ve-,

hicle equipped with the apparatus starts a trip. Its movement to such position is limited by means of a bearing 79 (Figure 2) fastened to the back of base 1 and associated with stub shaft 19. This bearing 79 also limits the movement of the flag 17 to the full line or projected position in said Figuresrl and 7 in which it indicates that the aforesaid vehicle is vacant. By movement of the flag to the concealed position, stub shaft 19 turns the disk 28 and accordingly arm 35 to the right which depresses contact 34 into engagement with contact 33. The switch arm 20 may also be thrown to the left for instance, so as to simultaneously engage the contacts 37 and 38, reference. being had-to Figures .9 and 4, particularly the latter.

Thus anelectric circuit from a source of cnergy such as an electric battery, is established through the motor 42 and the double electromagnet 64 and switch contacts 55 and when closed by the cam 54. Figure 4 illustrates the electric circuit as controlled by switch 22. When said switch bridges contacts 37 and 38, current flows from battery 80 through conductors and 82 to the motor '42, spreading'through conductor 83, contacts 55, a conductor 84, a conductor 85, electromagnets 64, a conductor 86, contact 36, a conductor 87, contact 37, switch 22, contact 38' and conductor 81 back to the motor 42 and at the same time spreads from switch 22 through a conductor 88, contacts 34 and 33, and a conductor 89, back tothe battery 80. As motor 42 operates,.its shaft 42 through the medium of the worm 5O drives gear wheel 49 which imparts movement to the shaft 46, gear wheel 51 thereon and gear wheel 52. The gear wheel 52 during rotation at cam 54 alternately engages and disengages the con tact 55 to move the latter with respect to contact 56 so as to alternately make and break the said electric circuit to thus periodically energize the magnet 64. By energization of the magnet 64, the armature 63 is alternately Retrograde movement of said shaft 59 is prcvented by the pawl 73 in cooperation. with ratchet wheel 72. After each attraction of the armature 63, and the breaking of the circuit to the electro-magnet 64, such armature 63 is restored to normal position preparatory to the next actuation hy the spring 2 Referring now to the registering mechanism, a bracket mounting therefor consistsof an attaching plate 91 secured to the base 1' and side plates 92 and 93 extending forwardly therefrom. A shaft 94 is journaled in saidside. plates 92 and 93 for rotation in from the wheel of a'taXicab when the motor 42 is idle. Said drums 14 on their periphery preferably have numbers delineated from Zero to nine as shown. Each drum 14 has a hub 98 projecting beyond the open side thereof'and a ratchet wheel 99 on and rigid With said'hub (Figure 13). Plates 92 and 93 mount a rod 100 on which a plurality of pawls 101 are pivoted which engage said ratchet'wheels 99'and are urged into engagement therewith by means of springs 102 surrounding rod 100,.each' spring having one end secured'intermediate the base 1 and plate '91 and the other end disposed over pawl 101.

' Shaft-94 (Figure 24) has alongitudinallyex tending groove 103 (Figure 24'), one wall of which is straight and substantially radially disposed and the other wall of which curves"- from the base of said wall to-the periphery.

Spring pressed 'pawls 104 are carried by the drums 14 and pass through suitable slots'in hubs 98 and enter the groove103.

7 An actuating frame(see Figures"? and:11)i

is provided comprising arms 105 and 106, ],ournaled on said shaft 94. These arms are joined by a rod 107 and thereon a plurality of fingers 108 are journaled from which the spring paw1'109 extends and engages said ratchet wheels 99. This frame is'urged for ward by means of a contractile spring 110 secured to arm106 and to a bracket or e'Xten-' s1on 111 pro ecting forwardly from the bear-- ingor plate 61-. 'Forward movementjof the arm 1.06 and frameof which it forms a part is limited'as by means ofa stop-in'the form of a set screw 112 mounted in a depending arm 113 of the bracket 67.

Rigidly secured on the shaft 59 is a cam 114 preferably provided with two points or lobesas best shown in Figure 13, which points are vadapted to alternately engage the arm 106 duringrotationof the shaft 59 in order to depress or move the arm 106 rearwardly. During rearward movement "of the'actuating frame, the pawl s 109 idle overthe ratchet heels 99 bu't when they are released, they engage the teeth 'of said ratchet wheels and advance the same on the return moyement of theactuating frame under urgency'oFthe spring 110. Itwill. beunders'tood that ;the

arrangement of the wheels 14 is such that viewing them in Figure '13, the innermost wheel first makes a complete revolution and then imparts movement to the central wheel and upon completion of its revolution, the

third wheel is act-uated,'the structure being but generally shown, details 'being omitted for the sake of clearance and as forming no part ofthe invention itself. After the 'pawls 109 advance the ratchet wheels 99-and wheels 14 rigid therewith, retrograde movement of said wheelsis prevented by the pawls'101 as will be understood. Journaledon the shaft 94 is a gear wheel 1 15 which is rigid with a relatively large disk 116 (Figures 5, 13- and I 16). On said diska spring, pressed pawl 117 is provided which cooperates with grooves 103. A stub Shaft 11s 'onthe side latters journalsa gear wheel 119 in meshwi-th said gear wheel and also in mesh with the teeth of a rack bar 120. Back bar 120slides against the inner longitudinal edge of asuitably shaped track member 121 overlapped by a guard flan-geor'bar 122. -The rack bar 120 i is provided with a cap member 123 (Figures 9 and 10), and a contractile spring 124 is securedat125 tosaid cap member and'xat 126 i to the track 121.

Said spring 124 normally maintains the rack -bar-120 in engagement with the lug 127 of a lever 128 provided wit-h' a' wedge end '129. Said lever 128 ispivoted' at130 on an arm 131 extending from the base 1 -(Fi-gnre 5). Thewedge end 129,115 shown in Figure 7, is interp'osed between the side plate "93 and "a slidable detent plate '94". Wedgelever 128 is urged upwardly by 'means'o'f a coi l spring 132 secured to said lever 128'and side plate 93. To limit downward movement- 'of lever loo 128, at one end, a set screw 133 is; provided which is ad ustable, as shown in Figure '5, in the pathoflug127.

Detent plate 94 is slidably mounted 7 means of set screws or the like 134 passing therethrough and intoa bar 135 mounted by and intermediateside plates '92and 93 ure 7). I The late 94 has elongated slots 136 through wiichisaid setscrews 134 passQ A contractile fspring'137 secured .to the plate 94 and guide plate 93 normally maintains the detent. plate: in contact with theiwedge 129.

or track member 121. l I The rack bar120 in any suitable manner operates the register 26 but primarily it is adapted to beactuated to resett-he number drums 14. To this end, an arm 140 (Figures 9 and 10) is extended. from disk 28 and has a lifting lever 141pivoted thereon at 142. A pin 143 is provided on arm 140 to which a spring 144 is secured which is also secured at 145 to the lever 141 in order to urge the lever 141 into engagement with the said pin 143 and receive it in a notch 146. As will be noted from Figure 9, when the flag 17 is raised, the lever 141 is at anangle to arm 140 and resting onthe arm 67.

The arm 106 as seen in Figure 7 V, is extended and provided with a cam 147, (also see Fig ure 11) to cooperate with a slot 148 in the detent plate 94*. Projections 138 cooperate with slots 149 in said detent plate in that the drums 14 may turnonly when said slots 149 aline with the respective projections 138.

The resetting operation is as follows. When the fiag 17 ismoved from the full line position shown, that is from the inoperative position to the operative or dottedline position, the disk 28, arm 140 and lever 141 move. Said lever 141 in its upward movement engages the cap 123, (Figures 9 and 10) thus sliding the rack bar 120 upwardly against the tension of the spring 124. In moving upwardly, said rack bar 120 disengages the lug 127, whereupon the spring 132 moves the lever 128 upwardly causing the wedge 129- to move the detent plate 94 to the right as in Figure 7 against the tension of spring 137, whereby the openings 149 will be disposed in the path of movement of the lugs 138 and thus will offer no obstruction to their rotation or movement. Continued upward movement of the rack bar 120 through the medium of gear wheels 119 and 115, rotates disk 116 independently of the shaft 94, with the pawl 117 idling over the shaft 94. Slight further movement upwardly of lever 141 fromthe position shown in Figure 10 will disengage same from the cap 123 whereupon the spring 124 will urge the rack bar 120 downwardly thus rotating the gears 119 and 115 and disk 116 in the opposite direction causing the pawl 117 to coact with groove 103 of shaft 94 to move the drums 97 to an initial or reset position. As the rack bar 120 descends it engages the lug 127, thus depressing lever 128 against the tension of the spring 132, lowering the wedge 129,- whereupon the spring 137 urges the detent plate 94 to the left disposing unslotted portions thereof in the path of movement of projections 138 to prevent further movement of the drums 97 until the succeeding operation.

The actuating frame for the number or registering drums moves rearwardly with the cam 114 and the foot 147 coacts with the adjacent walls at the recess 148to move the detent plate 94 to the right in Figure 7 so that the slots 149 will be in the path of movement of projections 138 so that the drums 97 may advance.

J ournaled in plate 93 is a shaft 153. This shaft is also journaled in the track rail 121 adjacent the lowerend thereof. A spring pressed pawl 120 (Figure 5) is provided on rack bar 120 so as to idle past a ratchet 149 on shaft 153 in one direction and sothat as said rack bar descends it will advance the ratchet wheel 149 to advance one of the reg istering wheels or drums 25 one number. A spring pressed pawl 150 on rail 121 prevents retrograde rotation of shaft .153 and pawl 149". Shaft 153 is further supported by bearings 151 in which both of the shafts 94 and 153 are journaled. On said shaft 153, the drums of the registering mechanism 24, visible through the opening 22, are journaled. The rotation of certain parts ofthe registering mechanism is controlled by idler gear wheels 152 journaled on shaft 153 and adapted to mesh with teeth 154 provided in the sides of said registering wheels. One por tion of said registering mechanism is adapted to be driven through movement of the actuating device of the registering drums 14. To this end, the shaft 94 has a ratchet wheel 155 journaled thereon with which a gear wheel 156 is rigid. The pawl 109 of the adjacent finger 108 is relatively wide and in addition to engaging said ratchet wheel 155 it also engages the adjacent ratchet wheel 99 so that both ofthese ratchet wheels will be simultaneously operated and will turn the gear wheel 156. The gear wheel 156 in turn drives a gear wheel 157 (Figure 11) journaled as at 158 to the adjacent plate. Such gear wheel 157 together with a gear Wheel 159 pivoted at 1.60 to the adjacent bearing plate 151, and a shaft 161 (Figures 7 and 11) has driving engagement in any desired way with the aforesaid. registering mechanism 24, specifically forming no part of the invention.

Said shaft 161 is mounted in side members or walls 162 and 163 of a suitable mounting bracket supported from the base 1 as by a lower wall 164. Gear wheels 165 and .166 are keyed on the shaft 161. A gear wheel 167 j ournaled at 168 on side members 162 meshes with gear wheel 165 to operate a part of said registering mechanism 24. .On the other hand, a gear wheel 169 journaled at 170 on side wall 163 meshes with gear wheel 166 to operate another part of said registering mechanism 24.

On shaft 161, a clutch head 171 is slidable having a sleeve provided with an elongated slot into which a pin on shaft 161 projects. Said pin extends from a sleeve 174, in tele scopic relation with clutch head 171. The sleeve 174 is carried by a gear wheel 175, keyed on shaft 161. On shaft 161, a clutch head 176 is provided having teeth 177 to cooperate with the teeth of the head 171 in order: that rotation of gear wheel may be imparted to the clutch head 17 6. The drivin :of gear 175 in v the manner aforesaid drives shaft 161, gears 165 and 167 and the latter operates the parts. of the registering mechanism 24. When the flag17 is raised, the clutch heads 171 and 17 6 are disengaged. Lowering of said flag engages clutch heads 171 and 176 since this movement causes slide 198 to be depressed, thereby causing engaging' movement of slide 189 and clutch head 171. With. the'clutch heads thus engaged, shaft 161. drives the gears 167 and 169 which results in driving other parts of'theregistering mechanism 24. In mesh with gear wheel 175, which is a worm wheel, is a worm 177 mounted on a shaft 178 journaled in the wall 164anda bearing 180 carried by bar 135. Belowwall 164 a gear wheel1'81 is keyed or fixed to shaft 17 8 and. retrograde movement thereof is prevented by means of a; spring pawl. 182 secured to the base,1. Journaled on the shaft 17 8 below the wall 164 is a lever 183, movement of which is limited in one direction by a pin 184 depending from wall armature 188 is mounted on thewlever 183, whereby upon energization of the magnet- 186, armature 188 will be attracted which 1 will cause the pawl 185 tofadvance the wheel 181 and impart movement to the shaft 178 and mechanism in' gear therewith.

In order to shift the clutch head 171 into and out of engagement with the clutch teeth 177, an actuating slide 189 is provided and movable on. the under surface of the wall 164 beingffastened by a set screw 190 disposed in'an'elongated slot 191 infthe slide 189. Passing from the slide through an opening '1 192 in the wall 164 is a fork or bifurcated arm- 193 which-engages in a groove 194 of the head 171.

The actuating lever or slide 189, as'best shownin Figures 7 and 15 receivesan arm of a lever 195 in the slot of a fork 196 on the slide 189. This lever is pivoted'at 196 to theside member 162. A spring 197 may be secured to the lever 195 and. bar 135 for nor- 7 mally maintaining clutch head 171' out of engagement with the clutch teeth 177.

A bar or slide 198 operable to depress the lever 195-is provided with elongated slots 197* through which set screws 198 (Figure 6) passto mount the same, one of said set screws enteringthe supporting, plate 39, and

the other entering a stud 199 on side plate 92.

'Adjacent the upper end of the bar 198 isa slot 200 into which alug 201 of a depressible actuating plate 202 extends. This plate is normally dis osed, in the position shown in Figure 17 and issecured' to the back ofthe supporting plate 39 by means of set screws or the like 203passing through elongated slots 204 in the plate. The action of spring 197 normally maintains the plate 202 in elevated position. Said plate 202 is. operable for de-' pr-ession into the dotted line position shown in Figure 17 so as to depress the bar 198, lever .195, shift the slide 189, and slide. the clutch head 171. The plate 202 is depressible as the flag 17 is thrown to the right when it is desired that the apparatus should operate, through the medium of a studor projection 205 on disk 28. When the flag 17 is raised, the clutch heads 171 and 176 are disengaged. Lowering'of'said flag engages clutch heads 171 and 176 since such movement causesslide 198 to be depressed, thereby causing engagement of slide 189 and clutch head 171. With theclutchthus thrown'in, shaft, 161 drives the gears .167 and .169, which results in driving certain totalizers or partsof the registering. mechanism'24.

conductor 85, magnet 64, and conductor 86 to the Contact 36. Thus both gear wheels under such circumstances, namely at 62 and at 181, will be driven by the cooperation therewith of theelectro-magnets and their armatures. In the circuit last mentioned however a make and break device is provided j so that the electro-magnets 64and 186 will alternately attract and repel their armatures. Such. a-device is diagrammatically shown in "Figure 4 and specifically shown in Figures Such device includesspaced V 19, 20 and 21.

contacts 209, normally disengaged and being 1 against one of them- The make and break device involving, said 7 'plic able'but only when the circuit of motor 42 is open or in other words only during engageable by the working of a finger 210 p Frunning time. A sleeve 211 may be provided, extending from a base plate 212, and

having a removable cover plate 213. The r plates 212 and 213 are secured together by means of set screws 214 passing through a spacing block 215 and into an arm. 216 which is in any suitable manner attached to; the wheel of thetaxicab or other vehicle as re-. ferred to. 1 The shaft carrying said finger 210, is provided, at 217 Rigid withshaft 217 is an actuating wheel 218 disposed inter mediate the bracket 216 and base plate 212. The wheel 218 has a plurailty of spaced leaves or spokes 219.

To cooperate with the wheel 218, a cam ring as shown in Figures 22 and 23 is provided, being attachable to the vehicle wheel concentric with the hub by means of bolts or the equivalent passing through tangs; 221 thereon. The cam track 220 r at its terminalsis connected by a plate 222 which spaces them apart. Wheel 218 isdisposed substantially radially with respect to cam 220 with the latter disposed between two of the spokes 219 as in Figure 19, whereby the cam in actuation serves as a spiral passing successively through the spaces between spokes 219 so that wheel 218 will thus be slowly rotated so as to impart its motion to the shaft 217'to close the contacts 209, to establish the electric circuit through the two magnets in a make and break manner.

A shutter 222 is adapted for disposition over the openings 12 and 13 when the flag 17 is raised and it may containthe wordVaca-nt thereon to be viewed through said openings, as suggested in Figure 7. lVhen the flag 17 is down, such shutter 222 occupies the dotted line position shown in Figure 11. It may also be mentionedfthat the sign 16 iscarried by the shutter 222 and is adapted to be displayed at the opening 12, as shown Figure 1, when'said shutter is in the dotted line posi-' tion of Figure 11, that is. lowered. Said shutter has an arm 223, which is adapted to engage the adjacent finger 108 when the shutter is disposed in the rear of opening 12 so as to move the adjacent pawl 109 out of engagement with the coacting ratchet wheel. 99, so as to enable resetting action of the wheels 97 to be effected.

The shutter 222 has side flanges 224 pivoting it at 225 to the side plates 92 and 93. One flange 224 has a lug 226 (Figure 6) which enters a slot 226 in an arm 228 secured to bar 198. Thus as the flag 17 is moved to the right and bear 198 is depressed, the

shutter will also be moved to its lowered position which will expose the sign 16 at open ing 12. I

As at times an extra fare or tariff is charged which is not fully indicated by the registering wheels or drums 14, a mechanism is provided whereby said registering wheels or drums 14 may be moved faster than normal as previously described in order to correctly show the fare. To this end, the stop screw 69 is carried by the aforesaid slide or bracket 71 which is secured in place d best seen in Figure 14, by studs 231 passing through an elongated slot 232 therein, and which fasten a plate 233 over the bracket 71 to retain the same in place. The bracket 71 is normally urged toward the armature 63 bya spring 234 secured to the bracket 71 and to one of the studs .131. A screw or connect ing member 235 extends from the bracket 71 to a swivel head 236 on a lever ..37 (Figure 9) pivoted'at 238 to the base 1. Movable against the upper free end of the lever 237 is a cam 238 and the lever is normally maintained in engagement with the cam by means of a spring 239 fastened to the lever and to a stub shaft 240 carrying the cam and which is ournaled on the base 1' and exteriorly' thereof has an operating handle 24 as clearly shown in Figure 2. In Figure 9, the parts are so disposed that the bracket 71 and stop 69 are set to limit movement of the armature 63 to the normal extent. In the event that it is desired to increase the price and permit the registering wheels or drums 14 to move more rapidly, the handle 24 is thrown upwardly into the position shown in Figure 10, thus moving the cam 238 as shown in said figure to a position tilting the lever 237 and drawing the bracket 71 away from the armature 63 which will provide greater space for its operation and consequently enable the ratchet wheel 62 to be turned to a greater extent each time the armature 63 is actuated.

A means is provided whereby extra charges may be registered and which means is preferably operable manually. It utilizes the drum 15 on the periphery of which suitable an'iounts may be delineated. Rigi d with he drum 15 is a ratchet wheel 229 wh ch is normally held against retrograde movement by means of a pawl 230 journaled on rod 100 and normally held in engagement with the ratchet by means of a coil spring 231 similar to the coil spring 102. For said drum 15 an actuating frame, is provided consisting of arms 232 and 233 loosely jour-i naled on the shaft 94 and on which said drum 15 is loosely ournaled. Thls actuating frame is normally spaced from cam 114 as shown in Figure 13 to avoid improper operation of drum 15 simultaneously with wheels 14. The drum 15 has a spring pressed pawl 234"" adapted to pass through a slot of the hub to engage the groove 103 of shaft 94. Said arms 232 and 233 are connected by roes or shafts 235 and on the rods pawls 236 and 237 are journaled. The pawl 236 engages the ratchet wheel 229, to actuate the wheel each time the fra is actuated.

Said pawl 237" engages a ratchet wheel 238 loosely mounted on the shaft 94 and having a gear wheel 239 rigid therewith which meshes with the said gear wheel 159 previously described in order to actuate the number drums 24. The drum 15 is normally held against retrograde movement by the detent plate 94 'when the actuating frame for the drum 15 is moved.

The cam foot 240 of the arm 233 engages a wall of slot 241 in said cam plate and slides the same so that a slot 242 in the detent plate Ice 'In order to Will be opposite the projections 243 on the drum corresponding to projections 138, so that the drum 15 may be advanced. In order that the actuating frame for the drum 15 may normally remain in and keep a forward position as in Figure 13,'a coil spring 244 isconnected to the extension 111 and to the arm 233 (Figures 7 and 8). A stop 245 to limit forward movement of the actuating frame for drum 15 is provided on the side plate 92. g

actuate the frame for said drum 15, a slide 246 (Figure 18) is provided havingan actuating plunger stub 247 which is slidable in an opening in the base 1 and projects to the rear thereof. The slide-246 also has an elongated slot 248 into whicha pin 249 mounted on side plate 92 extends. The slideor plunger 246 is capable of lateral play on the pin 249 in order that the hook or cam end 250 may be projected to the dotted line position of Figure 18 in order to move in front of and across the arm 232. The slide 246 is movable against the tension of'a spring 251 secured to the slide and to the base 1, preferably having its axisdiagonal so that as the slide plunger 246 is pushed forward, the-spring will urge front of the arm 232*. g

It will be realized that upon pressing the stub inwardly by means of the thumb or otherwise, the plunger 246 will move to the dotted line positionofFigure 18 and when released the spring will pull the arm 2L roarwardly a short distance, and then release it, whereupon the spring 244 will return the actuating frame for the registering drum' 15 to normal position. In this way, successive it toward and in operations of the plunger stub 247 will bring the desired extra amounts to be View at the opening 13.

charged into Briefly to resume the general operation and functions performed and'necessarily omitting much specific description as heretofore given, the electric wiring is so arranged that when said flag 17 is down as'in dotted lines in Figure 1 and full lines in Figure 2, and switch 20 is thrown to the right in Figure 1 and engages contact 36, the double electro-magnet 64 and the single electro-magnet 186 are connected in series with the battery 80. When such switch 20 is thrown to the left, it engages contacts 37 and 38 thus energizing electric motor 42 so that through the gearing shown, said gear 52 is also driven. Said gear 52 presses the cam '54 against the contact points'55 so that it engages contact 56 which causes the electro-magnets to attract their armatures and drive their respective sub-mechanisms or parts. Thecircuit at device 209--210 is operated from the wheel of the motor vehicle equipped with our improved apparatus and such device will be opened and closed a certain number of times per minute. Such closing of the circuit enwill always operate with the front wheel of the vehicle at device 209-210. Thus when the flag 17 is up none of theelectricalapparatus operates except magnet 186 which-it is to be noted is so connected that it operates irrespective of the position of the flag 17. lVhen the switch closes the circuit of motor 42, the latter drives gear 52 so asto close. the circuit at contacts 55 and 56'which causes magnet 64 through the gearing shown to drive shaft 59 which through cam 114, depresses actuating frame 105-106 to operate registering drums 14 thereby moving the third roll14 from the left in Figure 7 forward one number eachtime, after which the actuating frame is spring-returned to normal position. "Said drums 14 are so arranged that after said third drum from the left advances one number, the second roll from theleft advances one number and so on with the remaining roll until they complete the figures 66999,, I V H I The zero plate 16 asitis carried by the shutter 222 serves to lift and maintain lifted the control arm 108 (Figure 11) of actuate ing frame 105106 when thesaid shutter and fiag17 are raised so that when the, resetting mechanism .operatestheframe 10 5--106 to the third drum 14from the left, will not throw saiddrum' or the small gear connected to the registering rolls. When said flag 17 is raised, the slide 198 is moved upward can rying shutter 222 upward to, Vacant position'and pulls the clutch out thus disconnecting the registering mechanism. When flag 17 is thrown to the right, which turns disk 28, lifting lever 141, into engagement with cap 123. and thereupon lifting rack'bar 120 to a point, as in FigurelO where the lever. 141 disengages said cap and rack, whereupon the rack bar 120 due to gravity and theurgency of spring 124, descends and through coaction with the gear wheels shown picks up. the various fare drums or registering wheels, and drives them to normalposition, thus resetting such drums or wheels. The rack bar 120 also 'actuates lever 128 because of its wedge 129 so as to move the detent bar'or its starting position, arm 108. which throws I plate 94 to drum-unlocking position until bar has descended and the drums are reset. Then rack bar 120 pushes wedge 129 to one side and allows dctent plate 94. to slide in before, the projections 243 stop them; Also when the flag 17 is thrown to the right arm 35 depresses contact 34 against contact 33 which makes connections with battery 80. between the double electro-magnet 64 and the contact magnet device 209210 on the front wheel of the vehicle so that each time the cam at the said front wheel makes a contact, the armature 63 which through intermediate mechanism moves the driving shaft 59 on which is fastened cam 114 which depresses the actuating frame 105-106 a certain. distance each time. When a certain number of these contacts have been made, said cam 114 depresses the frame 105-106 to a point where they drop off and allow the frame to rise and carry the fare or registering drums forward.

The electric motor 42 and its contact arrangement is such that when the switch 20 is thrown to the waiting time side, the electric motor revolves and drives the gear 52 which closes the circuit of the double electro-magnet 64 and a certain number of times per minute causes the electro-magnet 64 to attract the armature and drive the shaft 59.

As to registering extra amounts, plunger 246 when pressed inwardly by the thumb moves to the dotted line position of Figure 18 and when released the spring 251 will pull the arm 232 rearwardly a short distance and then release it whereupon the spring 244 will return the actuating frame for the registering drum 15 to normal position. Successive operations will thus bring the desired extra amounts to be charged into view at the opening 13.
